DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.



Conditions for Clearing the DTC



DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.



Diagnostic Aids



P0641



The 5 V reference 1 circuit provides 5 V to the following sensors:



* B150 fuel tank pressure (FTP) sensor



* B17 barometric pressure (BARO) sensor, throttle inlet absolute pressure sensor



* B47B fuel rail pressure (FRP) sensor



* B1 A/C refrigerant pressure sensor



* All four B23 camshaft position sensors



P0651



The 5 V reference 2 circuit provides 5 V to the B26 crankshaft position sensor.



P0697



The 5 V reference 3 circuit provides 5 V to the following sensors:



* B74 manifold absolute pressure (MAP) sensor



* B107 accelerator pedal position sensor 2



P06A3



The 5 V reference 4 circuit provides 5 V to the following sensors:



* B106 throttle position sensor



* B107 accelerator pedal position sensor 1



瀚慖f the condition is intermittent, move the related harnesses and connectors with the engine operating. Monitor the scan tool 5 V Reference



Circuit Test Status parameters for the affected components. The Circuit Test Status parameter will change from OK or Not Run to Fault if



there is a condition with the circuit or a connection.
